Bourgeois class domination is undoubtedly an historical necessity, but, so too, the rising of the working class against it. Capital is an historical necessity, but, so too, its grave digger, the socialist proletariat.

The most revolutionary act is a clear view of the world as it really is.

Freedom for supporters of the government only, for members of one party only no matter how big its membership may be is no freedom at all. Freedom is always freedom for the man who thinks differently.

Only through the conscious action of the working masses in city and country can it be brought to life, only through the people's highest intellectual maturity and inexhaustible idealism can it be brought safely through all storms and find its way to port.

Those who don't move don't notice their chains.

Social democracy.. is only the advance guard of the proletariat, a small piece of the total working masses; blood from their blood, and flesh from their flesh.

We will be victorious if we have not forgotten how to learn.
